Answer:
Red: 1/2
White: 1/6
Blue: 1/3
Step-by-step explanation:
You take and find the total number of marbles, which is 18. You then take the number of each different color and make that number your numerator, and 18 your denominator and reduce.
Red: 9/18 reduces to 1/2
White: 3/18 reduces to 1/6
Blue: 6/18 reduces to 1/3

31.8755522675
Step-by-step explanation:
i pluged it into a site called desmos
Area of a triangle is = 0.5bh
if the height (h) is 4 less than base (b) then h = b - 4
48 = 0.5(b)(b - 4)
48/0.5 = b² - 4b
96 = b² - 4b
b² - 4b - 96 = 0
(b + 8)(b - 12) = 0
b must be either -8 or 12
since a distance can't be negative that means
the base is 12
Okay, well for a right triangle with legs a and b and hypotenuse c we have:
a2+b2= c2
since we know the hypotenuse (c), we have:
a2+b2= 25
since the short leg is 1 inch shorter than the longer leg,
we can say that a = b-1
So now we have:
(b-1)2+ b2 = 25
b2 - 2b +1 +b2 = 25
2b2-2b -24 = 0
2(b2-b-12) = 0
b2-b-12 = 0
(b-4)(b+3) = 0
Because you can't have a negative length, b = 4
If b = 4, then a = 4-1 = 3
So,
b=4
a=3
